does setting the fixed property of a Vector to true before entering a loop is better for performance?
View 6 RepliesI want to make a nested Vector, where i define the length of the nested vector too, someting like this:
var kb:Vector.<Vector.<Number>> = new Vector.<Vector.<Number>(4)>(4); // 4x4 vector
This line throws a compilation error - anyone knows, if this is possible?
I am trying to improve the frame rate of a game that draws many floor tiles. Currently, the floor tiles are vector graphics and stored as different frames in a movie clip. I wanted to experiment with rasterizing a floor tile and seeing if that would provide any frame rate boosts. I did this by converting one of my tiles (one of the frames in my movie clip) to a png and replacing the vector version of this tile with this raster version. I then tested two worlds--one filled with tile A (vector) and another filled with tile B (png).
In all my tests, world with tile A (the original vector version) outperformed the world with tile B. I am guessing that the reason I am not getting the expected performance gains is because I am still rendering the tiles in the old style and not using any strict bitmap drawing calls?why it is that this method fails to boost rendering speed? Would I have to switch my rendering code to strict bitmap draw calls?
I tried the benchmark on this site: Array vs. Vector vs. Linked list. It tests the performance of iterating over said sequences.Remarkably, iterating over a linked list is approximately 2.5x faster than a Vector.<int>. What is the reason for this counter-intuitive result?
View 1 RepliesSo, the actual act of scaling a vector object has a bit of a cost to the CPU, and so animating an object from one size to another has a significant cost -- but is there any additional cost for simply playing an animation that has previously been programatically scaled?
My initial thought was that if I took a character -- it's a little dude with a walk cycle, done in vector, and skooshed him to like 0.66 scaleX and scaleY then there would be some performance hit for even just playing his walk cycle in skooshed mode vs. playing it at normal size, but I can't manage to confirm my suspicion.
I'm building my first Flash website in a 1280x800 px resolution, fixed top-centered layout. I have a 1920x1080 px bitmap set as my background. I did it in 1920x1080 px size, because I want the browser to display it (the background) acording to the user's monitor resolution. The main content though buttons, images, animations, etc - are fixed (1280x800 px centered). So, how do I do this? I've been searching the web, but I only find instructions for liquid layout layouts and such, and I don't want liquid, just the background to adapt to the target monitor size.I use Flash CS5.5 (11.5.0)
View 17 RepliesAre you aware how to set a variable to true or false in AS3;
I tried
Code:
var flip:void = true;
But this is not recognized by AS3.
Is there a way to auto set smoothing for all bitmaps in the library? or at least for imported bitmaps?
View 1 RepliesJust new to As3. I can't set visibility of movieclip inside another movieClip
ActionScript Code:
player.vidImage.visible = true;
trace(player.vidImage); // shows - [object SimpleButton]
tracing player.vidImage show [object SimpleButton]. But can't set visibility true.
VidImage is physically placed inside player MovieClip.
Setting the text property of a flex DateField makes the selectedDate property of that DateField go to null.I need to set the text property so that I can use a particular format (DD-MMM-YYYY).
View 2 RepliesI have a clip which is basically a set of button clips. When a button is clicked it fades (i used the ._alpha property) and finally when its 0 alpha, it removes itself (by using _visible=0 property). It works perfectly. Now when another button is clicked. I wanted the button which is currently not visible to restore its visibility. But using _visible=1; just isnt doing it (pastbutton._visible=1;). I tried a lot of trouble shooting, trace shows that the correct button path of the last invisible button is stored in pastbutton. But still when the next line says pastbutton._visible=1 still it doesn't restore the target button which is stored in the pastbutton variable.
View 1 RepliesHow do you set the embedFonts property to true with actionScript? I am trying to have a font embedded (font symbol?) and I do not know how to set it with teh embed fonts property so it shows up in the .swf file.
View 2 RepliesSince i upgraded to Flashplayer 9.0.124.0 i've noticed that using textures on 3D Objects via the beginBitmapFill method and setting the smooth attribute to 'true' causes the player to hang a few milliseconds at random. Setting smooth to 'false', the player runs without any hang. I tested this on different machines. An upgrade to player 10 beta didn't cure the symptoms but the hangs appear less in time. Has anyone else such problems or an idea what is going on?
View 1 RepliesHow do you make the childAllowsParent property of an SwfLoader go from false to true, that is, how as a parent application do you set up security to make the child app's events and other properties accessible to you. To read the flex docs on this, one would think nothing could be simpler:
"This property [childAllowsParent] is set to true if the child object has called the allowDomain() method to grant permission to the parent domain or if a URL policy is loaded at the child domain that grants permission to the parent domain. If child and parent are in the same domain, this property is set to true . [emphasis added]" So, I'm in a development environment and want to load an swf from my own system via an SWFLoader and then be able to monitor its events within the parent app.

I need to loop a flv file in flash if a condition is true.
So I tryed to add a listener but id doesn't work.. Code below:
textBox.addEventListener(FocusEvent.FOCUS_IN, focusInListener);
var connection:NetConnection = new NetConnection();
var stream:NetStream;
var video:
Video = new Video(200, 200);
var metaObj:Object = new Object();

I want to leave the for each loop as soon as the boolean is set to true.

I've tried break and such, but this all doesn't work.
I have some issue with the [embed] tag. Even if I set the embedFonts property of the textfield to true the text doesn't show up.The thing is that it worked previously and after some changes (not related to fonts) it doesn't. I'd like to understand how the embed process for font works to find the error in my code.
I declare :
[Embed(source = 'asset/font.ttf', fontName="font", mimeType="application/x-font-truetype")] private static var font:String;
to assign the font to the program.Then i call "font" when declaring my textFormat. Is the "fontName" property the link with the textformat ?I work with flashdevelop and the flex_sdk_4.0.0.14159 (the big adobe one, with air (~140mo))

I am making a little flash animation, and for this one scene, I need an animation to loop over and over, while a soundtrack plays underneath.
My sound file is 867 frames long. My animation is 20. I want the animation to loop every 20 frames, and the sound to loop every 867. I tried with making the animation loop by itself, and it started the sound from the beginning every 20 frames. While the sound beneath it was still playing.
In other words, is there a way so that a sound layer is not affected by the looping of the animation?
If I have a MovieClip with its "visible" property set to "false", would it aid performance to "stop()" its timeline? Or will that have no effect, since its not being rendered, anyway?
View 3 RepliesSo for my current project I am to handle A LOT of objects on the screen. Which made me wonder what approach I would go about the ENTER_FRAME event.I have 2 samples below, one where my BulletControl object calls on every bullet object's 'FrameFunc()' in its own ENTER_FRAME event with a for loop.The other sample every object has its very own ENTER_FRAME, so it works independently.
[code]....
Also for each burst of bullets I create about 50 objects or so; a lot of object instantiation is never good with such a short interval which makes me wonder if the garbage collector has a hard time keeping up.
I have an array. I have a button, when I press on it I want to be able to loop through every item in the array and see if EVERY item is equal to true, if so I want something to happen.
var allIsTrue = false;
_global.myArray = [false, true, false, true, false, true, false, false, false, false, false, false, false,false,false,true]
///would not do something
[Code].....
I thought I could loop through each one and if a false statement if found, the loop stops and the variable allIsTrue = false. But if the loop cycles all the way through allIsTrue = true.
What I want is to sort a Vector array of objects(not primitive), based on a propery(Number). (think character.zDepth). Generally the same thing as the sortOn function of Arrays, except that we don't have that for Vectors.
like myArray.sortOn(x, Array.NUMERIC)
Dealing with Vector arrays of primitives not complex objects.
i am using soundmanager to order sounds. my site preview, in home page, square shapes comes into stage and you can drag drop them, all shapes binded its own sound. if they are colliding binded song will play.
the problem is i have 3 second timer to control sounds. every timeout i have to stop sound and play again for synchronous issue, that is my solution for that part. but sometimes before loop, there is an annoying little silence.
I have a swf within a html page. There is a function that opens an html page when an object gets to a certain x position. However, when the object gets to that point the new html page (in _self) opens over and over again and get stuck in a loop. Any way to escape this loop and what would be the best way to trigger this new html page to open when the x position of the object is true?

I was trying to create these 17 textfields in a for loop. I ended up instanciating them manually and now I am trying to set some of their properties in a for loop. The problem is that when I trace them I just see [object textfield] but not the names. If I try to trace the ".name" I get instance 1, instance 2, etc. The real problem is when I try to set the "y" property I get an error "1010 A term is undefined and has no properties"

View 5 RepliesThis marks a new chapter for me asking a question about an entirely different subject that I know nothing about I'm following a book called "Flash Games" and it's not for beginners and I'm a beginner so lots of jargon that I don't know and simple google searches don't come up with anything. What is the Flash IDE? Does this author mean the application Adobe Flash to build applications. So that means there is Flex, and Flash Catalyst, and Air IDEs? I don't really treat this like IDEs in terms of programmer but I guess I just don't know. The author says to set the document property on my file.fla to Game. How to do this?
